So is there any other difference between the slim and the phat then the size of the nand?

Think I read in the past that the smaller nand versions have parts of their firmware stored on hdd. So is it now just about to adapt it to the smaller nand size or will we get in trouble cause of the external storage of some part of the fw on hdd?

To quote, roughly translated: The first downgrade to 3.70 on PS3 Slim 3:55, DiGiTaLAnGeL tested by us!

For the first time, we have been involved in something truly spectacular We were the first in the world to test the downgrade from 3.70 to 3:55 on a PS3 Slim (With flash memory, "NOR") using the ProgSkeet and patched some files provided by dospiedra, a famous Spanish coder already riding high for having discovered the method of going back to 3.55/3.41 with the PS3 (FAT flash memory "NAND").

After several attempts, in collaboration with dospiedra, we got to go back from 3.70 to 3:55, enter the factory mode with a simple key to jailbreak, rifleshare a modified version of 3:55 to prevent the SYSCON (the registry in between downgrades) was consulted during the downgrade and now we are happily at 3:55 KMEAW!

With this version of moddata 3:55, you can perform a memory dump today and you can switch on the fly from 3:55 to 3.70 without having to do this all the time-consuming process: using progskeet fact you can go straight to 3.70 changed to 3:55!

Dospiedra said it will release details on the patches applied to the NOR and the update file as soon as possible.

New life for those who arrived too late to enjoy the benefits of the 3:55?

look we need to get the keys so we can sign our own homebrew and to create games and update files. someone has these keys already so give them out maybe not websites but chat with people and have it spread out idea xlink kai or something.. if some one has the keys email them to someone or something give them to me i'll go down for it.
